What? Me Worry?
You know...I totally ignored these but I've heard great things about them from the people who actually bought them....
That said, one of my friends who did buy one said that the comparable GURPS sourcebook would be a better choice if you were given a choice...not that the green books were bad or anything..just tha the GURPS books were better...
I disagree with that, a lot. The GURPS books are good, but are much more crunch-heavy than TSR's books. I think TSR's books go into much greater and better detail on their respective eras than their GURPS counterparts. GURPS has vast library of such books, though, covering just about everything, so they have TSR beat in that respect...but not in quality.
BTW, what era is Age of Heroes supposed to represent
Ancient Greece.
and does't A might Fortress overlap with Age of Charlemage and The Crusades?
No, not really. A Mighty Fortress is more the Renaissance era and a bit after.
